Filed: 1992-06-10
Abstract: PURPOSE:To provide an inverter unit having high control accuracy by measuring ON/OFF delay of inverter and performing control operation at a timing subjected to correction of delay. CONSTITUTION:A controller 107 detects variation time of DC side current Id, AC side current, or AC side voltage of an inverter 101. Signal propagation delay times of a drive circuit 106 and switching elements T1... are thin measured based on the difference between the variation time thus detected and a time when ON or OFF driving signal is delivered.

Title: Method for detecting change of scenery
Inventor: HOJNACKI SUSAN M
IPC: G06T7/20
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To eliminate necessity to exactly overlap an image before a subtraction step by specifying the pixel of a first image and a pixel at the same position in a second image to select the maximum values of first and second differential pixel values. SOLUTION: While using any one of ordinary digital image processing image overlapping techniques, two images are overlapped (S44). Next, a change between the first and second images is determined by specifying pixels X0 and Y0 of the first image and pixels X1 and Y1 at the same position in the second image (X0=X1, Y0=Y1) (S46). Continuously, concerning respective differential pixels, any arbitrary boundary can be set for suppressing the amount and strength of the change to be detected (S50). In order to display the image together with an instructed difference (S54), the color images (in red, green and blue, for example), of three bands are generated.
